[0058] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0062] In existing parking air conditioners, when there is relative motion between the vehicle and the outside air, the airflow around the heat exchanger outside the vehicle is fast, which causes the temperature detected by the outdoor unit's temperature sensor to be lower than expected. If the temperature detected by the outdoor unit's temperature sensor is so low that it differs significantly from the air conditioner's set temperature, the air conditioner controller will determine that the cooling effect has been achieved, thereby reducing the compressor's operating frequency and making the cooling effect worse. The low control precision of the parking air conditioner affects the user experience inside the vehicle.

[0063] This invention creatively proposes a control method for a parking air conditioner, including determining the deviation ΔT of the detected external temperature at different times and judging whether ΔT is greater than T. y1 When ΔT≥T y1 At that time, it was determined that T needed to be... n Compensation; where T y1 The first preset temperature, T n For the outdoor unit temperature sensing bulb at t n It continuously monitors the external temperature of the vehicle, improving the control precision of the parking air conditioner, ensuring the user experience inside the vehicle, and solving problems such as low control precision and poor cooling effect of existing parking air conditioners.

[0066] This embodiment provides a method for controlling a parking air conditioner, such as... Figure 1 As shown, the parking air conditioner includes an outdoor unit 1 installed outside the vehicle and an indoor unit installed inside the vehicle. The outdoor unit 1 includes a base 14, a housing 11, a fan blade 12, a heat exchanger 15, a compressor, and an electrical box 13. The base 14 is located on the top of the driver's cab, and the housing 11 is placed on the base 14. An air inlet 111 is formed on the side wall of the housing 11, and an air outlet 112 is formed on the top wall of the housing 11. An air duct is formed between the air inlet 111 and the air outlet 112. Along the air flow direction, the heat exchanger 15 and the fan blade 12 are arranged sequentially in the air duct. By controlling the rotation of the fan blade 12, outdoor air can enter the air duct through the air inlet 111 and exchange heat with the heat exchanger 15, and then be discharged through the air outlet 112. The compressor and the electrical box 13 are installed on the base 14. The fan blade 12 is on the windward side, and the electrical box 13 and the compressor are on the leeward side. An outdoor unit temperature sensor is installed on the housing 11 to detect the temperature of the outside environment.

[0087] Where n≥2, T y2 The second preset temperature; T y2 = -3℃;

[0088] Thus, based on the detected temperature of the external environment, the system dynamically adjusts whether to adjust the T... n This compensation improves the accuracy of determining the reference temperature of the external environment.

[0089] To address the issue of the inability to accurately determine the reference temperature of the external environment, this embodiment proposes that the control method further include:

[0090] S6. When it is determined that T needs to be... n During compensation, determine T c =T n +k*T b When it is determined that T is not needed n During compensation, determine T c =T n ;

[0091] Among them, T c T is the reference temperature of the external environment of the vehicle. b The preset compensation temperature is given by k, which is the temperature compensation coefficient. b and T n Determined and k≥1;

[0092] Thus, based on the detected temperature of the external environment, the system dynamically adjusts whether to adjust the T... n This compensation improves the accuracy of determining the reference temperature of the external environment.

[0093] To address the issue of inaccurate compressor operating frequency, this embodiment proposes that the outdoor unit includes a compressor; the control method further includes:

[0094] S7, according to T c Determine f;

[0095] S8, Control the compressor to run at f;

[0096] Where f is the target frequency of the compressor;

[0097] This improves the operating efficiency of the parking air conditioner and avoids the problem of inaccurate compressor operation caused by inaccurate reference temperature of the outside environment.

[0098] This embodiment also provides a control device for the parking air conditioner control method described in any of the above claims, comprising:

[0105] When it is determined that the vehicle is in a parked state, it is clear that no action is required on T. n compensate;

[0106] When it is determined that the vehicle is in motion, the wind speed in the external environment is considered to determine whether T needs to be adjusted. n compensate.

[0107] Furthermore, the parking air conditioner is also equipped with a wind speed sensor, which detects the wind speed outside the vehicle; based on the wind speed outside the vehicle, it determines whether the T-zone needs to be adjusted. n Compensation includes:

[0108] The wind speed V detected by the wind speed sensor at the current moment is collected. j ;

[0110] When Vj ≥V y At that time, it was determined that T needed to be... n Compensation; when V j <V y When it is determined that T is not needed n compensate;

[0111] Thus, based on the different conditions of the vehicle, it can be accurately determined whether T needs to be adjusted. n Compensation improves the accuracy of determining the reference temperature of the external environment.

[0112] Example 3

[0113] In this embodiment, n = 2, then ΔT = T2 - T1;

[0114] When ΔT≥T y1 At that time, it was determined that compensation for T2 was required;

[0115] Where T1 is the temperature of the outdoor unit's temperature sensor at time t1; T2 is the temperature of the outdoor unit's temperature sensor at time t2.

[0116] Specifically, the time difference between t1 and t2 is one minute, T1 = 35℃, T2 = 31℃, ΔT = 4℃, and T y1 =3℃, ΔT>T y1 ; Determine that the vehicle is currently in motion, and confirm that compensation for T2 is required. b =3℃; Determine the reference temperature T of the external environment of the vehicle. c =T2+T b =34℃; then, based on 34℃, the target frequency of the compressor is determined, and the compressor is controlled to operate at the target frequency.

[0117] After running for a period of time, T2 and T1 are collected again, and it is determined whether ΔT is less than T. y2 ;
